TOA Systems Global Lightning Network® (GLN®) is an advanced lightning detection network providing high quality real-time lightning data to assist business operations for our clients globally. With lightning sensors strategically located at international sites, data from the GLN has the timeliness, coverage, and flexible delivery to support critical business operational requirements without compromising quality, accuracy, and efficiency.

There are many instances where disruptive weather events put people and property at risk, and additional weather coverage can be vital to improving the outcome of these events. While lightning has significant value as a supplement to radar for identifying and evaluating convective activity, it is an essential source of information where radar is not available. Data and services from the Global Lightning Network are a major component of the solutions meeting these weather information needs.

Lightning knows no borders

The Global Lightning Network offers full global lightning detection with extensive coverage of Europe, South America, Australia, South-east Asia, including many areas where lightning has significant economic and safety consequences. Data is also available for oceanic and other continental regions. The network continues to expand and be enhanced with additional sensor host sites.

Every second counts

By taking advantage of TOA’s proprietary lightning detection technology and our re-sellers extensive processing and distribution facility’s, data is delivered without delay, with diverse format and delivery options facilitating integration into existing systems and applications. When time is of the essence, real-time streaming data is available via the Internet in 20-30 seconds from detection.

Complete and accurate information

The GLN provides the most comprehensive real-time data including individual cloud-to-ground strokes. Since a consolidated flash report can consist of multiple strokes, full stroke data delivers the detailed and uncompromising accuracy our customers require. In addition, our lightning sensors are designed to detect and differentiate between cloud-to-ground and cloud lightning events. Detecting both types of events provides a better overall picture of the storm activity and allows improved analysis of storm development and decay.
